En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:

nfc: nfcmrvl: validar la longitud del comando auxiliar antes de pull

La ruta de recepción de la descarga de firmware elimina la cabecera de datos NCI y lee el comando auxiliar antes de validar la longitud restante del paquete. Por tanto, un marco corto puede llegar al acceso a los datos antes de que el paquete malformado sea rechazado.

Validar la longitud completa del comando auxiliar antes de eliminar la cabecera de datos NCI.
